Double kill. but actually you can change it up from time to time and the showcase for calling cards is nice. Personally I've been rocking the calling card for cooked grenade kills with the little grenade on the side with a chef's hat. It's funny and I don't think I've ever seen anyone else with this card. (Not saying that there aren't others who haven't gotten it, just haven't seen anyone else use it).
I don't remember what those two look like, but my favorite is the one with the camouflage background and gold dog tags on the right (forget how I got it). I also like the Escort one for Defending a Flag carrier, but I can't seem to get it because CTF is pretty much dead on PC and the ones who do play it are new or really bad and never take the flag.
